Hello All,

I need to use the KTP 700 F Mobile panel to write data in an S71516 F CPU in TIA V13 SP1 Upd9 (my project), and in another CPU IM 151 8 F that is in a seperate Step 7 5.5 project that is know how protected (Supplier project, cannot modify code, cannot go online). 

Now both CPUs are on the same profinet network and have I-device communication configured to exchange normal data and Failsafe data. On this same network, i have two MP boxes. one in the supplier machine where the IM151-8 F CPU is located, and the other MP box is in my control cabinet where my S71516 CPU is located.

I need to do the following:

In my KTP700 F i have a screen that should be displayed if my KTP700 is connected to the supplier machine MP box. In this screen i need to use buttons to modify a data block in the IM 151 -8 CPU. How can I connect the tags form my KTP700 to modify data blocks in the IM151-8 CPU,

Any body has an idea?
